Specification of Letters Patent.

Patented Aug. 1, 1916.

To all whom it may concern Be it known that we, STAFFORD CALDWELL.

and CHARLES J. WILLIAMS, citizens of the United States, residing, respectively, at Live Oak and Atlanta, in the counties of Suwanee and Fulton, and States of Florida and Georgia, have invented new and useful Improvements in Air-Distributors, of which the following is a specification.

This invention relates to air distributers and more particularly to air distributers for electric fans.

The principal object of the invention is to provide a simple, eflicient and inexpensive device of this character which will distribute the air from the fan over a relatively large area and which will prevent excessive drafts and yet produce a proper circulation of air.

Another object of the invention is the provision of a device of this character which concentrically arranged frusto-conical rings 3 outwardly inclined and attached together by means of the cross wires 4 having loops 5 at opposite terminals to which one end of the springs 6 are secured. The opposite ends of the springs 6 carry S-hooks, so that the distributing device may be attached to fan casings of different sizes, said hooks be ing ordinarily connected with the rear guard bar of the cage. When a device of this character is applied to the fan air will be radiated in all directions from the center of the fan and distributed over a large area, which will be approximately five times as great as the'area of the fanwithout the distributer.-

It will, of course, be understood that these distributers may be made in any size or that they may be made in the form of concentrically arranged frusto-conical members, rectangular in outline. The preferred form, however, is illustrated herein.

What is claimed is In combination with a fan having a cage, of an air diffuser, mounting bars rigidly secured to one side of said difl'user, and trac tion springs connecting said bars with the rear of said cage, said bars being greater in length than the diameter of the cage whereby the line of tension will be toward the axis of the cage for the purpose described.

In testimony whereof we afiix our signatures in presence of two witnesses. STAFFORD CALDWELL. CHARLES J. WILLIAMS. Witnesses as to Stafford Caldwell:
